Shareholder Return Information

The following performance graph compares the cumulative total return on our common stock for a period beginning October 25, 2004 (the date our common stock began trading on the NYSE) with the cumulative total return of the Standard & Poor's 500 Stock Index, and a peer group of companies selected by us.

Our 2008 peer group is comprised of Agrium Inc., CF Industries Holdings, Inc., Potash Corporation of Saskatchewan Inc. and Terra Industries Inc. Our stock price performance differs from that of our peer group during some periods due to differences in the market segments in which we compete or in the level of our participation in such segments compared to other members of the peer group. In accordance with Standard & Poor’s policies, companies with less than a majority of their stock publicly traded are not included in the S&P 500 Index, and, accordingly, we are not included in the S&P 500 Index on account of our controlling stockholder. The comparisons set forth below assume an initial investment of $100 and reinvestment of dividends or distributions.
